digging machining parts

Each roller shaft is machined by the utilization of the most modern technological advances known to the industry, Grinding and finishing methods ensure mirror like finish and tempering with medium to low frequency heat treating equipment guarantees maximum strength.

Maximum life

Each roller shell is carefully heat treated to ensure long wear life and stress resistance.

Precision care

Each roller is precision machined to house special high impact low wear bimetal bushings.

In the process of assembly of roller, the expected and reliable sealing and lubricating rotation of roller are guaranteed by testing of air pressure tightness and load-bearing rotation.
